_& WARNING
You or your passengers could be injured while
changing a wheel if you do not follow these
safety precautions:
- If you have a flat tire, move a safe distance
off the road. Turn off the engine, turn the emergency flashers on and use other warn­
ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­
ing changed. When one front wheel is lifted
off the ground, placing the Automatic
Transmission in P (Park) will
not prevent the
vehicle from moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary, use a
sturdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment
